Abstract

This experimental research examined the effect of CO2 as a diluent on the laminar burning speed of propane-air mixtures. Combustion took place at various CO2 concentrations (0% to 80%), different equivalence ratios (0.7<?<1.2) and over a range of temperatures (298 K to 420 K) and pressures (0.5 atm to 6.2 atm). The experiments were performed in a cylindrical constant volume chamber with a Z shaped Schlieren system, coupled with a high-speed CMOS camera to capture the propagation of the flames at speeds up to 40,000 frames per second. The flame stability of these mixtures at different pressures, equivalence ratios, and CO2 concentrations was also studied. Only laminar, spherical and smooth flames were considered in measuring laminar burning speed. Pressure rise data as a function of time during the flame propagation was the primary input of the multi-shell thermodynamic model for measuring the laminar burning speed of propane-CO2-air mixtures. The laminar burning speed of such blends was observed to decrease with the addition of CO2 and to increase with the gas temperature. It was also noted that the laminar burning speed decreases with increasing pressure. The collected experimental data were compared with simulation data obtained via a steady one-dimensional laminar premixed flame code from Cantera, using a detailed H2/CO/C1-C4 kinetics model encompassing 111 species and 784 reactions.
